Abstract (en)
[origin: EP0224896A1] To permit more effective viewing during dental surgery or diagnosis, a retractor or probe assembly (12) includes: a cylindrical stainless steel handle (21) about 14 centimeters long and 7 millimeters in diameter to which a mirror (30) may be mounted; and a 15 millimeter long retractor or probe (20) extending at right angles to the handle with openings in it for the passage of light and an opening near the retractor or probe for water and air. One end of the handle opposite to the retractor or probe receives an air hose (28), a water hose (29) and a fiber optic bundle (26) connected to a dental light source to supply air, water and/or light to the retractor or probe end of the handle. The retractor or probe assembly: supplies light with sufficient intensity for transillumination or direct illumination of the dental root, pulp chamber, or other constricted areas in the oral cavity; and in the case of a blade shaped retractor, is strong enough to permit insertion into and retraction of the gingival tissue or other oral soft tissue.
